Answer:

Step-by-step explanation:

The area can be found by sectioning the polygon into three shapes. A rectangle with an area of 18 inches can be found at the bottom, while the top can be divided into two triangles. The triangle on the left has an area of 18in^2, (1/2*6*6) while the triangle on the right has an area of 9 in^2 (1/2*6*3).

Total area for all three shapes is 45 sq. inches

The difference between Sheila and Robbie's ages is 12. The sum of their ages is 42. If Sheila is the younger of the two, how old

Colt1911 [192]

Let's say that Robbie's age is represented by r and Sheila's age is represented by s. Since we know that r is greater than s, we can set up a difference equation of r - s = 12. We also know that r + s = 42. Now, we can simply add the two equations and get that 2r = 54, then finally that r = 54. Therefore, Robbie is 54 years old.

Hope this helps!

Answer:

$-4$

Step-by-step explanation:

Step 1: Apply the rule

$\left(-64\right)=-64\\\\=\sqrt[3]{-64}$

Step 2: Apply the radical rule

$\sqrt[3]{-64}=-\sqrt[3]{64}\\\\=-\sqrt[3]{64}$

Step 3: Factor the number

$\:64=4^3\\\\=-\sqrt[3]{4^3}$

Step 4: Apply the radical rule

$\sqrt[3]{4^3}=4\\\\=-4$

Therefore, $\:\sqrt[3]{\left(\:-\:64\right)}\:=\:-4$

Fernanda is filling a cylindrical pot with cans of vegetable soup. The pot has a diameter of 15 in. and a height of 11 in. The s

Answer:

45 cans

Step-by-step explanation:

To find the volume of a cylinder, we need to find the area of the cross section, which in this case is π(radius)², and multiply it with the height of the cylinder

This means the pot has a volume of:

- pot has radius of 7.5in. as diameter is 2 x radius

π x (15/2)² x 11 = 618.75π in.³

The soup can has a volume of:

- soup can has radius of 1.5in. as diameter is 2 x radius

π x (3/2))² x 6 = 13.5π in.³

Divide the volume of the pot by the volume of the can to get how many cans of soup will it take to fill the pot:

618.75π in.³ ÷ 13.5π in.³ = 45.833... cans

The question states you need to round to nearest can which would be 45 cans, but personally, I thought you would always round up as 45 cans won't fill up the whole pot, but it's up to the question.
